Similar characters of reference are used to denote likeparts throughout the accompanying drawings.

Referring more particularly to the drawings the letter A. represents a harvesting machine and binder of any well known approved modern construction which embodies the usual supporting frame structure B to which is attached my improved shocking mechanism C. y

Track rails 1 and 2, which in this instance are shown. to be of l beam construction and formation, are disposed longitudinally of one side of the harvester machine and below the binder deck plate thereof. These track rails are rigidly supported in a parallel horizontal position with respect to one another through the medium of suitable braces 3 which are secured tothe harvester frame structure B in any suitable manner.

Mounted upon the track rail 2 is a slidable frame 4, the opposite ends of which are shown to embrace the track and its fianges so as to firmly support the frame member in a vertical position and yet allow of a free slidingl movement backward and forward upon the track. As clearly shown in Fig. 4 of the drawings the slidable frame 4 is shown to consist at its forward end of a vertically disposed frame bar 5, the lower end of which embraces the upper flange of the rail 2 as indicated at 6, while the upper end of the bar 5 is offset as indicated at 7, and securely attached to the under side of the movable binder deck 8, so that it will slide with the binder deck when it moves forward and backward, inL order that the shock former will always be in proper position to the bundle tying needle. Secured to the bottom portion 6 of the bar 5 is a horizontally extending stop arm 10, which eX- tends rearwardly of the arm and is curved downwardly as indicated at 11 to form an effective stop, for a purpose which will presently appear. The rear portion of the frame embraces the track rail 2 as indicated at 12 and then extends upwardly and forwardly in the form of a supporting bar 13, which eX- tends forwardly above and in substantially parallel relation to the track 2, and then eX- tends upwardly to a point adjacent the bar .5, where it is provided with an offset flange 14 similar to the flange 7 that is designed to be attached to the underneath surface of the sliding binder deck. rin arcuate'bar15 exe tends downwardly and forwardly from the flange 14 and is connected to the bar 5 intermediate its ends. The rear portion of the bar 13 is provided with an upwardly extending curved arm 16, that is also offset at its upper end and is secured to the binder deck 8. At the juncture of this arm 1 6 with the bar 13, there is formed a recess 17 for a purpose which will presently appear.

Mounted upon the inner face of the frame 4 is a horizontally disposed rock shaft 18, that is journaled in suitable bearings 19. The rocker arm 2O is fixed upon the shaft 18 and has connected to its inner end the rod 21, which is connected at its opposite end to a crank arm 22 fixed upon the needle shaft 23, that is common to any harvester of modern construction. The opposite end of the rocker arm 2O is offset laterally and providedwith a roller 24. From this it will be seen that every time -the needle shaft is rocked, in the operation of tying a bundle of grain, the rocker arm will likewise be given a rocking movement corresponding to the tying of each bundle. i

A carriage D is mounted upon the track railsl and 2 for movement backward and forward of the length of the machine. This carriage is shown to consist of a cross bar 25 at the rear end thereof which is connected to supporting hangers 26 and 27. Journaled in the upper and lower ends of the hanger 26 are flanged supporting wheels 28, that have their opposite ends connected together by a brace bar 29 so as to hold and retain these flanged wheels upon the track rail 1.

The inner forward portion of the carriage is supported by flanged wheels 30 that are journaled in the opposite ends of a hanger 31, while the opposite journal ends of the wheels 30 are supported in a bracket 32 that is connected to the bar 29 of the brace bar 33.

A rocker shaft 34 extends transversely of the carriage and has one of its ends journaled in the hanger 31 and its opposite end journaled in the end of a supporting arm 35 which extends longitudinally of the frame and is rigidly secured to the cross bar 25.

Mounted upon the inner end of this rock shaft is an enlarged rocker arm which is shown to consist of arms 36 and 37, the outer ends of both arms being provided with friction rollers 38 and 39.

As shown the harvester A is shown to embody a revolving, shaft 40 which is of ordinary and well known construction used in connection with the mechanism for driving the conveyer mechanism, as indicated clearly in Fig. 2 of the drawings. This shaft 40l extends longitudinally of the binder and has mounted thereon a worm hub 41, that is provided with a set of worm threads formed in two different pitches 42 and 43, one of which is a continuation of the other.

i The friction rollers 38 and 39 are designed and adaptedV toengage this set of worm threads, during the movement of the carriage froman extremeyfront to anextreme rear position. As shown the worm threads 42 have a very slight pitch, while the threads 43 `have a greater.. pitch, by which it will be seen that as the friction roller 38 engages the threads 43, in the movement ofthe carriage from the front to the rear of the ma- `chine, that the carriage will travel back equivalent` to the speed at which the harvester is traveling forward` until the roller has reached the end of the threads 43, wherelthe roller ,39 will be disengaged and `from this it will be seen that the movement the limit of its forward movement, the

rocker arm 37 is rockeddownwardly so thatthe friction roller` 39 will engage the worm thread 46from which it will be seen that the same continued rotation of the worm hub 4l will be used to drive the carriage rearwardly to the limit ofthis movement,

or in other words to a shock discharging po- -s1t1on. As the thread 42 is of such a slight pitchiit will be apparent that the car will move forward at a very slow `rate of speed in order that theshoek former arms will have time to pass `over the shock before being closed.

Extending transverselyT of the carriage D is a rock shaft 47 `which has its inner` end journaled in the frame har 35 and` its outer end supported in the triangular hanger 27 andthe connecting-bar 48. The outer end of this roel; shaft 47 is formed with the right angular extension trip arm 49 that extendsiforwardly of the carriage, and is` designed to be tripped or moved upwardly to `swing the friction pulley `39 downwardly into engagement with the worm thread 46 in-,order tounove the carriage rearwardly of the machine.

The outer side ofthe carriage D is supported `upon the track, rail 2 for movement by flanged rolle-rs 50 that arejournaled between and in the opposite ends of the trianguiarv hanger 27 and the connecting bar 48.

` Journaled in the lower end of the triangular hanger 27 is a flanged, roller 51 which bears and rides on the underneathsurface of the track rail 2 in order to retain the carriage in position upon the track `rails at all times under various conditions that may exist in the operation of the shocker.

Mounted `upon the :rock shaft 47%is a rocker arm 52 which extends forwardly thereof and is connected by a link to the arm 54 of a substantially T shaped trip arm, which latter is fixed upon the rock shaft 34. This trip arm embodies additional arms 55 and 56, the arm 56 extending oppositely to the arm 54, and has connected toits outer end a link 57, the opposite end of which is connected to one end of a retractile spring 58, which in turn is attached to the cross har 25 of the carriage.

From the relative position of the parte shown in Fig. 7 of the drawings, it will be manifest that the retractile spring 58 exerts an upward tension on the arm 56 ef the "i" shaped trip arm, which in turn hasthc tendency to rock the shaft 34 and thereby cause the friction roller 38 carried by the arm 36, which is secured to the opposite end of the shaft 34, to be held in engagement with the worm thread 45.

By the time that the carriage has reached the limit of its forward movement, or in other words a shock receiving position, the friction roller 59 carried by the end of the arm 55 will have engaged beneath the rclease trip 60 mounted upon the binder arm and ridden down the inclined face 61 thereof a sufficient distance to rock the arm 55 downwardly and rearwardly and conse quently move the friction roller 38 upwardly out of engagement with the thread 45, to a position substantially as shown. When the parts are in the position shown in Fig. 7, it will be apparent that neither of the friction rollers 38 or 39 are in engagement with the worm threads, from which it will-be apparent that the carriage will remain at rest until a sufficient number ofl 05 bundles of grain have been deposited within the shock former to form a complete shock.

`Immediately after the completion of the formation of the shock, the trip arm 49 is moved upwardly, which in turn will move the rock `arm 52 upwardly, rock the 'l' shaped trip arm until the pivotal center of the connection of the rod 57 with the arm 56 has passed below a line drawn through the rock shaft 34iand the connection ef the retractile spring 58 with the frame bar From this it will be seen that when` the trip arm 49 has been moved upwardly a sui'licient distance, the` friction roller 39 will be moved quickly downwardly into engage .ment with the reverse thread 46 of the `worm hub, which will immediately reverse the movement of the carriage and move the same rearwardly into a shock discharging position. i'

As soon as the carriage has reached a shock discharging position, the friction roller 59 of the arm 55 will engage the inclined face 62 of a stop 63 that is mounted upon the binder frame in a suitable manner. By

a slightly further movementV of the carriage, or in other words when the carriage has reached the limit of its extreme rearward movement, the roller 59 will have ridden down the inclined race 62 suiiiciently to discngagc the friction roller 39 from the reverse thread L16 and immediately ca use the friction roller 38 to descend into engagei nient with the thread 4-2, which will immediately canse the carriage to start forward to its initial shock receiving position.

lflrtending transversely of the carriage and mounted in bearings 0i upon the cross bar 25 is a shaft 65 which is provided at one end with a bearing Harige 0G to which is rigidly `connected a supporting arm 67, that exi ends in angular relation to the shaft G5, a .r which is designed to support the shock torna-nj. li? found desirable the shaft 65 may be removed .irom its bearings by moving` the pin (lo which passes through the collar 69 mounted upon the opposite end of the shaft. lFoi-ined integrally with and extending at right angles to the supporting arm 67 is an extension arm 70, the outer end of which is crn'ved arouately and provided with a liriction roller 71 that is designed to engage and ride within an arcuate slot 7 2 formed in the horizontally extending bar 13 of the slidn able 'frame et. Secured to the supporting arm 67 adjacent its outer end is a brace arm 73 which is provided at its outer end with a friction roller 74 that is designed to ride down the inclined 'tace 7 5 and seat within the recess 17 of the slidable lrame 4L, when the shock former is moved to a receiving position, as clearly shown in Figs. 3, aand 5 or the drawings. This arm is intended to help support the weight oi the shock former at its outer end.

liei'ierring more particularly to Fig. 10 of the drawings, it will be seen that the upper or outer free end 67 is curved to form an angular extension 7 6 which has secured thereto a bearing 77 that is provided at its lower end with a circular flange 78.

Extendingv vertically through the bearing 77 is a vertical movable shaft 79 which has mounted upon its upper end an operating `lever 80 which is connected to a belt crank trip arm 81 by a rod 82. This trip arm 81 is provided with a bearing roller 83 that is designed to engage a trip, which will presently be described, in order to cause the shaft 79 to move vertically through the bearing 77. This .trip arm 81 is pivotally mounted upon an extension 84E of the supporting arin 67.

The vertically movable shaft 79 is pron vided with a slot 85 into which projects a set screw 86, that is threaded through the upper end of the bearing 77, and which is designed to limit the vertical movement of the shaft 79.

Attached to the under face of the circular flange 7S by bolts or screws is a circular cavity 88, in which is seated for rotation an annular ring 89 that is connected to the upper end of the sleeve 90 that is formed centrally upon a hood 91, bysuitable screws or bolts. As shown the hood 91 is circular in cross section and the walls extend downward] y and outwardly to provide an inclined surface 92, the lower end of the circular wall is then formed to extend vertically down ward so as to provide an annular shoulder 93. A head block 94 having a plurality yol: radial arms 95, as shown in Figs. 10 and 13 is disposed within the hood 91. Each of these arms 95 are provided with slots 96 in which are pivotally mounted, as indicated at 97 the upper ends or the shock former arms 98.

As clearly shown in Fig. 10 of the drawings, these arms are formed to provide substantially vertical extensions 99 that are designed Vto conform in shape to the inner surrace or' the hood 91 and when in their normal position are designed to lie flush therewith. These extensions 99 are formed integrally with a horizontally extending portion 100 that extends radially to a point beyond the hood 91, where they are connected to the arm 101 that extends downwardly and outwardly and are provided at their lower ends with inwardly and radially extending supporting arms 102, which are of substantially rectangular frame like formation, and `are designed to support the butt ends of the shock positioned within the former. Each 100 oit the arms 101 are'provided adjacent their lower ends with inwardly and radially eX- tendinp; separator arms 103, that are designed to separate and hold the bundles in the relative position shown in Fig. 15 of 105 the drawings by dotted lines.

Extending longitudinally of each arm 101 and journaled in bearings 104 thereon is a rocker rod 105. Arranged upon each rocker rod 105 in spaced relation, and ad- `110 jacent the lower end thereof, is a pair of clamping arms 106 and 107. Each of the clamping arms 106 has one end of a retractile spring 108 connected to it, while the opposite end of the spring is connected to the inner radial end of the supporting arm 102. The normal tendency of this retractile spring 108 is to swingthe clamping arms into the clamping position around the bundles of grain that have been deposited within the shock former and remain in such position until the shock Jformer has been arranged in discharging position, when these clamping arms are automatically opened and disengaged from the shock.

The upper end of each shock former arm is i provided with a right angular extension arm 109 that carries a friction roller 110 at its inner end. y

Mounted upon the lower end of the ver- 130 ticallymovableshaft 7 9 is a cam plate 111, thatfis of substantially circular formation, aswill tbe clearly seen -by refcrenceto Fig. 14 of the drawings. This cam plate`111 is provided with an upwardly andinwardly inclinedvflange 112, which `is designedto be engaged by the friction rollers 110. As clearly shown in Fig. Hof the drawings, the inclined flange 112 is cut away to provide an lentrance opening 113. The cam plate 111 is provided with an offset right angular cam flange 114 that is formed inte-4 grally with the cam flange 112 at one end, and terminates `at its offset end adjacent the entrance opening 113. l As the `shock former is rotated, in filling it, the cam rollers which are allonthe outside ofthe cam flanges 112 and114 will consecutively enter the passage 113, after the bundles have been placed withineach compartment of the shock former, by virtuecf the retractile springs 108, until each and every one of the cam rollers 110 have entered and are positioned entirely within the cam flange 112. The last of the camlrollers positioned upon the outer surface of the cam flange 112 will enter the passage 113 immediately after the last bundle of grain has been dropped into position within the shock former. By each and all of'these cam rollers entering within the circumference of the cam flange 112 "it will be apparent that as each one does, the clamping arms106 and 107 will be swung from an open position into a clamping position around the bundles contained within the shock former.

Byreference to Figs. lll' and 15 of the drawings, it will be obvious as each cam roller 110 passes around the-outer surface of the flange 112, that they will consecutively ride outwardly and around the eXtensionl cam flange `ll, so as to open the clamping arms 106 and 107 the full limit of their movement in' order that the bundle or bundles may be quickly and readily dropped into position within the shock former.

Again referring to Fig. 10 of the draw-` ings it will be seen that the head block 91 is provided with a tubular sleeve 115Y which is slida-bly mounted upon the shaft 79 betweenthe cam plate 111 and aA collar 116 keyed to the shaft and disposed' within the recess 117 formed in the upper portion of the head block. The sleeve 115 is provided intermediate its length with a circular flange 118 that is provided with a peripheral upstanding flange 119, which is designed to bear against the inner 'surfaces of the shock former arms, or the vertical extensions 99 thereof, and to hold the` same in a rigid position against the inner inclined surfaces 92 of the hood 91. l

Each of the shock former arms 101 has a rod 120 connected to the horizontal portion 100 and projects upwardly through an opening "in Ia supporting lug or plate 121 that 4projects laterally from the hood 91. The upper free end of -each of these rods 120 is threaded and is provided with a ball `bearing `member 122 which is held thereon by a nut 123.

1n the opera-tion of theshock former in the act of discharging the bundle from the shock former, and bearing in mind the fact that all of the c am rollers 110Vare positioned within the cam flange 112, the initial movement in `the device is for the shaft 79 to move' downwardly until the stop collar 116 rests upon the upper end of the tubular bearing 115, from which it will be seen that this movement is sufficient to disengage the cam flange 112 from the cam rollers, and which by a further downward movement will cause the peripheral flange 119 to be disengaged from the vertical extensions 99. After this initial movement takes place, the continued movement of the shaft 79 will force the head block 9-1, together with the bearing sleeve 115 downwardly until the bearing balls 122 rest upon the supporting brackets 121, after which by a continueddownward movement ofthe shaft 79 the arms 101 will. be forced outwardly so as to disengagc the supporting arms 102 from beneath the shock, as clearly shown by the dotted lines in Fig. 10. These bearing balls 122 act as fulcrums on which thelevers are swung outwardly.

AImmediately`after the shock has been discharged from the shock former, the shaft 79 moves upwardly, the first initial movement 100 of which carries the cam plate 111 to a position so that vwhen by a further upward movement, the shock former arms 101'are 'swung inwardly, the cam rollers 110 will engage the outer surface ofthe peripheral flange 105 112. As the shaft 7 9 moves upwardly to the limit of its movement, or to its normal position, the cam. rollers 110 will move around the` flange 112, thus rocking the, right angular extension arms 109 outwardly suil'ii- 110 ciently to allow the shock former arms to move inwardly to their initial position, which also at the same time cause the clamping arms to immediately open, which latter are fully open when they pass around the extension cam flange 114.

y Again` referring to Figs. 13 and 15, it will be noted that our improved shock former is shown' to consist of a plurality of radial eX- tending `arms, which are pivotally mounted in the head block 941 preferably, as shown,

the shock former consists ofsiX radial arms, two of these arms are so constructed that when positioned within the head block, they will lie in direct alinen'ientwith one another. 125 Each pair of arms that is disposed on opposite sides of the aliningarms areoifsetlat- `erally in opposite directions to provide a double `bundle receiving space therebetween, y and also to provide a single bundle receiving l space between each of these offset arms and each of the alining arms. From this it will bc seen, by reference to Fig. 15 that the shock former is designed to receive eight bundles of grain, as clearly indicated by the dotted lines, each bundle being dropped into the shock former in such a manner that the flat sides thereof will be positioned innermost of the shock.

Mounted upon the top of the hood 91, is a double ratchet wheel 124 which is provided in its peripheral edge with two sets of ratchet teeth 125 and 126, the teeth of one ratchet being disposed and formed reversely of those of the opposite ratchet. This ratchet wheel 124 is provided centrally with an opening 127 in which is mounted a circular head plate 123 that is provided with a central openin designed to receive the tubular bearin s eeve 90. This head plate is provided with oppositely extending arms 129 and 130, whereby the head plate may be rotated. The arm 129 has connected to it a retractile spring 131, which latter is connected to a bracket arm 132 that is secured to the shoclr former supporting arm 67. The arm 130 is provided with a ratchet pawl 133 and is designed to lockingly engage the ratchet teeth 125, as clearly shown in Fig. 12 of the drawings.

` Rotatably mounted upon this head plate 123 is an additional. head plate 134 and is formed with a trip arm 135, the outer end of which extends in angular relation to the arm as indicated at 136 and is provided with a trip lug 137 which is pivotally mounted in the end thereof, said lug being only movable outwardly of the extension 136, and designed to engage a stop shoulder when moved in the opposite direction in order to retain it in the position shown now. This trip'arm 135 lies in the same plane with the arm 130 and is disposed directly behind it. Pivotally connected to the outer end of this trip arm 135 is a rod 138 that is in turn connected to an arm 139 that is fixed to a rock shaft 140, which latter is journaled in one end of the bracket 132. This shaft 140 is journaled at its opposite end in a bearing 141 secured to the supporting arm 67 adjacent its pivotal connection with the carriage D. The lower end of this rock shaft 140 is provided with a bifurcated rocker arm 142, one of the arms 143 formed by the bifurcation being curved upwardly and inwardly, as clearly indicated ih Fig. '9 of the drawings to provide a bearing surface whereby the friction roller 24 carried upon the outer end of the rocker arm 20 will positively engage the arm 143 and ride into the bifurcation of the arm 142. In other words the arm 143 is so shaped that in case it has moved down to any position of lts range of movement by the starting of the needle to form a new bundle before the and in opposite directions are arms 144 and 145, the arm 144 being provided in -its outer end with the pawl 146 that is ldesigned to engage the ratchet teeth 125, while the outer end of the arm 145 carries the pawl 147 having a trip shoulder 148 that is designed to engage the ratchet teeth 126.

This ratchet mechanism designed for the purpose of rotating the shock former one notch at a time so as to receive the bundles consecutively one after the other until eight bundles have been tripped into the shock former. It is to be noted that there is a ratchet tooth in the ratchet wheel for every bundle to be deposited within the shock former.

IIn the operation of this ratchet mechanisrn and by particular reference to Fig. 11 of the drawings, it will be seen that the parts are so positioned to indicate that the shock former has received a bundle, and rotated suiiiciently to receive an additional bundle. As the bundle tying needles are projected through the deck plate 3 of the binder in the operation of tying a bundle, the needle shaft 23 will be locked, which in turn will pull on the rod 138, this movement drawing the trip arm 135 over toward the left, which latter being in the same plane with the arm 130 will move it over to the left until the ratchet pawl 133 engages the first ratchet tooth 125, this operation extending the retractile spring 131 connected to the arm 129. After the bundle tying needle has performed its function and moved back through the `deck plate 8, a reverse motion will be imparted to the rod 13S, which will move the triparm 135 over to the dotted line position shown in Fig. 12 of the drawings. As the trip arm 135 moves over to this dotted line position, the trip lug 137 will engage the shoulder 148 of the pawl 147` and release the latter fromthe ratchet tooth 126. As soon as this ratchet pawl. 147 has been released from the tooth 126, the retractile spring 131 will* irrimediately retract and rotate the ratchet wheel in the direction of the arrow a distance sutlicient to receive an additional bundle in the shock former. This action of the spring 131 will bring the parts into the saine relative position as shown in Fig. 11 of the drawings, since the pawl 146 is pivotallv i `wheel is rotated a distance sufficient to receive a single bundle'. In' the operation in this instance, the arm 130 carrying the pawl. 133will be moved over beyond the second tooth of the particular pair of teeth to the full extent of its movement. 'This being done andf there being no t'ootlil `for the pawl 133to immediately engage, the spring 131 will move the pawl 133 around the periphery of the ratchet wheel until it` engages the second tooth of the particular pair of teeth in question, fronrwhich it will be seen `that the pawl 133 will simply rotate tlie ratchet wheel et' one ratchet t'ooth,-or a distance sufficient toreceive the second bundle inthe double bundle receiving compartment of the shock former.

1n: the .operation ofthe device and referring more particularly to1 Figs. 1 and of the drawings, the shock former which is supported b v the' movable' carriage l), t'ogether with Ythe slidable ramel are shown in theact of moving' forwardly of the harvester" to al shock' receiving` position.

In" Fig. 5 of" the `drawings the carriage together with thev slidable frameYV has been shown in shock receivimgV position, or i'n other words in the limit of its forward movement, and'is urgedto start onit's` inner rearward movement.` 'llhe'limit of tlietirst initial rearward` movement of' `the carriage Carrying' the shock former supporting arm and operation o1 the latter'is" imlicatcd by tlie dottedlines shown in the" above'E nientioned Fig;l 5.

Briefly describing the operation of our improved Shocking mechanism, they shock former is' positioned i,orwardli7 ofthe'harvestei'f as indicated; by the position of its supporting carriage shown inFig. oft the drawings. Assuming 'the' shoclfform'cr to `bein this' positiomit is rotated step by step by the ratchet mechanism arranged upon the top of the hood* 91 through the medium of its connection with the needle rock shaft E253,

clearly shown in Fig. 2 of' the drawings.

In tlie operation of the' lnirifestcr and binder,- the"bun'dle tying" needle passes through the binder deck*` plate" and ties a bundle of grain, `after which" the bundle is discharged downward to the incli'nedfdecl plate into one of the compartments of the shock former. Immediately after thisbundle has been tied and placed within the shock` former, the bundle tying needle moves back-throughthe ileclrgplatmand as a result rocks the needle shaft which by its connections with the rocheI arm through the medium of' the link 21, will cause the rocher arm 20fto` move upwardly at its inner end and downwardly at its outer end. 'linie downward movement of the outer end oli' the rocher arms 20, will cause the friction roller 24,1Tig. 9, to descend upon the cuiwed upper face of the arm 143 and ride into thc bijturcation ot the rocher arm 1li/3, and which by 'a continued downward movement will cana the shaft lll() to roch in its bearings and move the rod 13S inwardly7 through the incdiumo the arm 139. rllhis rod 131i lacing` connected to the trip arm 1.35 olf lhointello mechanism will cause the ratchet wheel 12 torotate one step, or a distance suliicient to receive one bundle olf onlin. ll`roin`this it will be seen that immediately utter each bun dle has been tied and deposited inthe shock former, the `receding action ol: the bundle tying needle will cause the shock toriner to rotate one step.v orto a position to receive another bundle.`

Als the shock former rotates, the cam rollers 110 will ride ove'r the cam Hanne 11i which will cause the clamping arms ll'l and 107` of each compartment to fully open" to receive the bundle or lnindles, Clern-mclino,` upon' the compartment that happens to be in bundle receiving),-` position. After the bundle has been deposited in ils particular compartment and the shock former has been rotated one step, the cam roller governing; clamping-1" arms oit that particular conujiart-` ment will ride around the cam linneo 1l-l until it comes into communicaliion` with the passage 113, where the cam roller will be immediately forced through the ijiassap'e 1l to a position on the inside ot the cam 'llano` 112, through the inediumolf the retractilc spring;- 108, .which will in turn cause the clampingg'arms 106 andlO? to aulomatically a. L 'l close and clamp the bundle or bundles into the particular coinpartment. This operation as abovedescribed taires place consecutively until the shock former has been. filled with bundles. or in other words until eight bundles'have been deposited therein.

As soon as a bundle has been deposited in the last vacant compartment oil" the shocl-i former. a trip arm 1419 attached lo the arin 1051 of this last compartment, will move up wardly, will be understood" by reference tov Fig; 1 of the drawi into engem-uncut with the trip arm 49. The upward moveliient of this trip will rocli the shaft il?. movel the arm 52 upwardly. which in turn will roclt the shaft czuisinfj; the bearino' roller 39 carriedl by the arm 37 to descri downwardly into engagement with the worm thread 36 of the worm hub 41, which will immediately cause the carriage D carrying the shock former to immediately move rearwardly to a shock discharging position.

Referring to Fig. 5 of the drawings :it will be seen that in the first initial rearward movement of the carriage that the friction roller 71 carried by the extension arm. 70 of the supporting arm 67, will ride down the arcuate slot 72 in the slidable frame 4, `it being understood that at the same time that this roller 71 is moving downwardly that the carriage is moving rearwardly beneath the roller 71, so that by the time the carriage has moved rearwardly `a sufficient distance to cause the roller 71 to have moved to the end of the slot 72, the supporting arm 67 will have been caused to move to a vertical position as indicated by the dotted lines. rfhis movement is accomplished very quickly owing to the great degree of pitch of the worm thread 43.

As soon as the shock former has been moved to this upright position it is carried onrearwardly to a shock discharging position by the worm thread 43, and at the same relative speed at which the harvester machine moves forward in the operation of harvesting the grain.

Just before the bearing roller 39 has reached the end of the thread 43, the friction roller 83 carried by the trip arm" 814 will come into engagement with the downwardly and arcuately inclined iiange 150 of a trip plate 151 which is fixed to the web of the track rail 2 in any suitable manner. By a continued rearward movement of the carriage the friction roller 83 will move down the surface of the flange 150 sufliciently far to rock the trip arm 81 and hold down upon the rod 82, which in turn will cause the shaft 79 to descend vertically through the medium of the arm 80 connected thereto. This descending movement of the shaft 79 will cause the shock former arms to be released and spread radially and outwardly to disengage the supporting arms 102 and the separator arms 103 from the shock, thus allowing the shock to drop a short distance to the ground, so as to settle the bundles together.

By the time that the roller 39 has reached the end of the thread 43, the shock will have been discharged, the roller 39 disengaged and the roller 38 engaged with the thread 42, which particular set of threads will cause the shock former to move forwardly, and we will say for the purpose of illustration, the distance of five inches, while the har vester is moving forward a distance of five feet. From this it will be seen that the shock former arms will have plenty of time to pass over the shock before the mechanism to be hereinafter described, proceeds to close the arms.

In the preferred construction of the shock former, it is to be understood that each of the supporting rods 120 increase in length gradually from a position directly in the rear of the shock former, around the circumference of the shock former, so that when the arms are spread from beneath the shock, each arm will consecutively, from a point directly forward of the shock former, and around the circumference thereof, be moved outwardly and upwardly a little more than the preceding arm. From this it will be noted that the rear arms are swung upwardly to a position so as to readily clear the top of the shock that has been dropped to the ground, as the shock former again moves forward to the harvester.

Again referring to Fig. 5 it is to be noted that when the shock former has reached the position shown in dotted lines, and the roller 71 reached the rear end of the arcuate slot 72 that a continued rear movement of the carriage and shock former will move the slidablc frame 4 rearwardly to a shock discharging position, as clearly shown lin Fig. 3 of the drawings, so that the shock former will be in the proper position to the bundle tying needle.

As soon as the shoclehas been discharged from the former, the shock former arms moved over the top of the shock and moved radially inwardly to a closed position, the shock former immediately begins to descend from a vertical position to a substantially horizontal position, or to the position shown in Fig. l2 of the drawings, this is accomplished by the friction roller 7l riding up the arcuate slot 72 in the slidable frame 40, which frame remains relatively stationary while this movement takes place. As soon as the shock former has reached the horizontal position as shown in Figs. 1 and 4 of the drawings, the carriage together with the frame 4 is moved forwardly of the harvester, through the medium of the thread 43, to a bundle or shock receiving position.

It is to be borne in mind that immediately after the shock former has been moved from a discharging position to a substantially horizontal position, that the friction roller 83 Carried by the trip arm 81 comes into engagement with the stop lug 11 formed on the member 10, which by its contact with the friction roller 83 holds the shaft 79 in its elevated position, or a position which holds the cam plate 11 in a fixed relative position with respect to the cam rollers 110. As the shock yformer moves forwardly, or in other words as it is descending to a horizontal position, the friction roller 83 of the trip arm 81, will engage the arcuately curved ange 152 of the trip plate 151. As the shock former continues forwardly, this friction roller will ride up over the arcuate flange 153, *thus rocking the shock former has been moved to a horizontal position, the friction roller 834 will have come into contactwith the stop 11 and remain in engagement therewith throughout the movement of th-e shock former to a shock receiving position, and which will serve to hold the shock former arms closed during the voperation of dropping the bundles into the shock former. l

Attached to the forward end of the harvester machine and extending to one side thereof is an arcuately curved supporting plate 154 that is designed to support the butt end of the bundles forming the shock that has been rocked into the shock former. This supporting plate 154 is provided medially with a longitudinally extending rod or stubble guard 155, which is designed. to prevent the stubble from whipping the butt end of the shock.

Referring to Fig. 2 it will be seen that we have provided means to assist `in discharging the bundle from the deck plate into the shock former and is shown to consist of a vertically disposed arm 156, pivotally mounted at its upper end to the knetter frame construction 157, which is of the ordinary well known construction. A finger 158 is pivoted intermediate its ends to the lower end of the arm 15G, and pivotally connected to the outer yend of the finger 158 is a rod 159, which extends upwardly and is pivotally connected to the knetter frame as indicated at 160. As shown the finger 158 is pointed and extends in the direction of the bundle tying needle, so that as the bundles are tied and gravitate down theinclined deck plate, they will come into engagement with `the pointed end of the finger 158, which will swing outwardly under the weight of the descending bundle and by virtue of its engagement therewith,

cause the bundle to swing outwardly and properly drop into the shock former as it leaves the deck plate.
